Also in the movie, Cooper should have been dead by the time he reached the accretion disk because it would’ve been incredibly hot. Once he was just close enough, he along with his spaceship should’ve gotten ripped apart, or spaghettified. Spaghettification happens when gravity pulls harder on the side closest to the black hole than on the further side. If you were falling in a black hole feet first, gravity at your feet would be much stronger than the gravity at your head, so you would get pulled and stretched apart molecule by molecule.
Overall I think this is a really great movie and I very much enjoy watching it over and over. Movies like this are cool because it, at least for me, really sparks my curiosity. I just think about why some things are.
